USP Underlayment

High Performance Roof and Wall Underlayment

Air Barrier Membranes

SRP breathable membranes are multi-layer, spun bonded materials that control moisture intrusion and accumulation in the wall and roof assembly. SRP membranes resist water and air penetration while allowing water vapor to escape.

Installed in sloped roofing systems as a water vapor permeable air barrier and secondary drainage plane. Ideal for use in insulated, sloped roofs covered with metal, clay, cedar and other systems requiring an underlayment or slip sheet.

Black air barrier with long term UV resistance. Designed specifically for use with open jointed rain screen cladding systems including slotted wood siding, panel systems, and other “open joint” systems where resistance to UV exposure is needed.
